Shrinking the transistors to a smaller size should offer efficiency gains that mean power users will require fewer cores.However, gamers who might be tempted should be aware that many titles cannot take advantage of more than four cores.Intel has made 28-core chips before, but those Xeon series processors were designed for high-end computer servers rather than an individual's use.Are two screens better than oneImage copyrightAsusImage caption Asus's new Zenbook Pro replaces the trackpad with a touchscreen Image copyrightAsusAsus also revealed a range of new laptop computers with two screens.The trackpad on its new Zenbook Pro has been replaced with a 14cm (5.5in) touchscreen that can display photographs, menus and tools such as a calculator or calendar.
There was also a concept laptop with two screens instead of a keyboard, which the company has called Project PreCog.Image copyrightAsusImage caption Asus is developing laptops with two screens "Even in laptops, the goal is to be all screen," said Isa Rodriguez, from the technology site Gadget Match.Over-hypedHowever there was disappointment when Lenovo revealed its new Z5 smartphone.Image copyrightLenovoImage caption Lenovo had suggested the Z5 would be "all screen" In May, the company had shared images online that implied the phone would be "all screen" on the front, rather than having the "notch" that appears on the iPhone X and imitators.Critics said Lenovo had posted misleading images and that the actual announcement was "disappointing"."The new phone, which was teased to be a nigh bezel-less display without a notch or a chin, has debuted with both of them present," wrote Michael Allison, from news site Neowin.Chinese phone-maker Vivo may instead become the first company to release a genuinely "all screen" phone.
It plans to unveil its Nex phone - which features an in-screen fingerprint reader and a selfie camera that pops out of its side - on 12 June.
